English threading the common name for bsa; the b standing for british. The shell is 68mm wide, the inner diameter 34mm, with the threading reversed on the drive side.
Choose between two bearings for the crank. Standard bearings have low drag thanks to hardened-steel races and our ceramic balls. Coated bearings have those same balls installed on coated, hardened-steel races for longer life and less bearing drag.
